Abstract EN
A decentralized sewage treatment reactor was designed to treat wastewater in rural areas.
To examine the factors influencing nitrogen removal, experiments were carried out at three levels of hydraulic surface load, three sludge concentrations, and three environment temperatures at low dissolved oxygen concentrations.
The rate of denitrification decreased, and the rate of nitrification increased as the surface load rose.
The maximum denitrification rate was 20.01 ± 3.02 g/(m3·d) at a surface load of 1.11 ± 0.13 m3/(m2·h).
The total nitrogen (TN) removal, efficiency initially increased and then decreased as the sludge concentration rose.
When the sludge concentration increased to 3.5 ± 0.3 g/L, the system showed a good level of TN removal and a denitrification rate of 28.58 ± 1.22 g/(m3·d) was achieved.
Low temperature had a negative effect on the removal and transformation of nitrogenous pollutants.
